The company runned by Mark Zuckerberg has introduced plans about big changes inside a mobile Facebook app, so the work is carried out on the possibility of using the application without an Internet connection.
This would involve a similar way as operating the mobile aplications with maps, generally that we would get the opportunity for downloading in advance current content of Facebook and later without an Internet connection freely browse the content of the application.
Users will have the ability to comment on posts on app but under condition that the comments would only appear after next reconnection with Internet.
It should however, take into account the fact that if the company will implement those changes, the application will take up more memory on your phone because it would have to store the data retrieved from the application server.
